CW Call Sign Weight Analyzer
This is a useful tool when trying to figure out how long it will take to send a
call sign using CW. The greater the weight of the call the longer it will take to
send it. You can enter multiple call signs separated by spaces or new lines and
the call sign weight analyzer will return them sorted by the lightest weight (or
quickest to send) call sign first.
